To show people what sorts of products can be improved by nanotechnology, educators often use stain resistant pants and tennis balls that retain their air longer. My mom called the toasty feet insoles to my attention. Blogger Marlene Bourne ranked them as one of the top ten consumer products that make use of nanoparticles.

From the aerogel website, "Aerogel, the advanced nonporous material in Toasty Feet, has the highest thermal insulation value of any solid material available today, allowing it to retain heat efficiently, while remaining light and thin enough to fit comfortably in almost any shoe or boot."

I would lean towards calling this a clever use of materials science rather than nanotechnology. The lines between those fields are often quite fuzzy. In any case, they look like some nice insoles.
